Diagnosis Murder Easter Egg - Squad 51

Watch the Diagnosis Murder episode "Malibu Fire".
(Originally aired on Oct. 2, 1997. Main plot was
that there was a HUGE fire and Dr. Sloan & Co. are
called out to help with the injured. Son Steve Sloan is a cop, and volunteer firefighter.)
Two guest stars in this episode were Randolph Mantooth and Robert Fuller, better known as "John Gage" and "Dr. Kelly Brackett" from the old TV series "Emergency!"
Randolph Mantooth plays the Mayor of one of the towns threatened by fire, but he's also a volunteer fireman.
Several times they show a shot of the fire truck he's with: It's Truck #51.
(In "Emergency!", John Gage was a Paramedic with Station / Squad / Truck 51).
